Pescri~tion ~f the Pre$erred Embodiment~
Now with re~erence to Figure 1, there is shown in cross-section one end portion of a multi-compartment container 10 ~or the storage o~ two dif~erent material compositions which are stored separately and which are mixed or put together at the point o~ delivery ~rom the container. Typical materials might be dental preparations, ~ood pastes, or two-part adhesives.
The container 10 comprises an outer compartment 11 ~ormed within a substantially tubular housing 12, and an inner compartment 13 ~ormed within a substantially smaller diameter tubular housing 14. The inner compartment 13 is eccentric relative to the outer compartment 11 as opposed to being coaxial or concentric thereto.
The two tubular housings 12, 14 are pre~erably ~ormed from ~lat ~lexible plastics strip, typically having wall thickness o~ between 0.2 and 0.5 mm and comprising a laminate o~ several layers o~ dif~erent plastics materials including a vapour-impermeable barrier which is typically a layer o~ a plastics material or a layer o~ aluminium ~oil. The strip is generally formed from high density polyethylene-based materials and the barrier layer is generally based on an ethylene vinyl alcohol material. The strip is rolled into a CA 02237878 1998-0~-13 W O 97/18138 PCT/GBg6/02721 round or oval shape with overlapping edges o~ the strip being welded together to ~orm a substantially round/oval cross-section ~lexible tube, which is subsequently cut to the desired length.
Each tubular housing 12, 14 in use has a closed end (not shown) which is formed with a ~ish-tail type welded seam as is commonly known in the art. The two closed ends may be ~ormed so that each tube 12 or 14 has a respective end closure seam or the two closed ends may be welded together in a single welded end closure seam.
The other end of each tubular housing 12 or 14 has a respective shoulder piece 16 or 17 located therein and which has a respective outlet nozzle 18 and 20 therein ~or expulsion o~ material from the tubular housings 12, 14. The two shoulder pieces 16 and 17 are moulded ~rom a high density polyethylene compound.
The outer tubular housing shoulder piece 16 has a lower cylindrical side wall 19 which is a close ~it within an end portion o~ the outer tu~ular housing 12. The upper end o~ the side wall 19 extends into a rounded edge 21 leading into a frusto-conical shoulder 22 tapering inwardly and upwardly away ~rom the side wall 19. The upper end portion of the tubular housing 12 is then heat ~ormed and welded to the shoulder 22.
The radially inner end of the ~rusto conical shoulder 22 has the outlet nozzle 18 projecting axially there~rom. The nozzle 18 comprises a second cylindrical sidewall 23 coaxial with the ~irst sidewall 19, projecting coaxially upwardly and terminating at its upper end in a radially inwards projecting shoulder 24. A second ~rusto-conical portion 26 extends upwardly and inwardly away from the shou1der 24 and terminates in a cylindrical ori~ice 27 coaxial with the sidewall 23.
A substantially diametrical partition 28 extends across both the orifice 27 and the nozzle 18 dividiny them into two passageways 31 and 32 each having a substantially semi-CA 02237878 1998-0~-13 circular or D-shaped cross-section. The lower portion o~ the partition 28, on that side which, in use, receives the outlet nozzle 20 o~ the inner compartment 13, may have a shoulder 29 ~ormed therein.
The inner tubular housing shoulder piece 17 has a substantially D-shaped lower side wall 33 which is a close ~it within an end portion o~ the inner tubular housing 14 which is o~ a general ~lexible oval construction. The upper end o~
the side wall 33 has a rounded edge 34 leading into an inclined shoulder 35 The inclined shoulder 35 slopes inwardly away ~rom the sidewall 33 and extends upwardly to define the outlet nozzle 20 which has a substantially D-shaped cross-section.
The inner tubular housing outlet nozzle 20 is a close ~it within outlet passageway 32 and at its inner end abuts the shoulders 29 on the partition 28 and the shoulder 24 on the outer shoulder piece 16. The inner nozzle 20 has a bead 36 which may be a continuous bead or an interrupted bead, on its external sur~ace which engages a like-contoured groove 37 on the inner sur~ace o~ the outlet passageway 32 to form a snap-~it connection between the inner nozzle 20 and the partition 28 and part o~ the sidewall 23 o~ the outer shoulder piece 16.
A closure 40 is ~itted over the outer shoulder piece 16 which acts as an external housing ~or the container 10. The closure 40 comprises a base 41 which is secured to the shoulder piece 16 and a lid or cover 42 which is hinged to the base 41 by a hinge 43 located at one side o~ the closure.
The base 41 may comprise two parts, an inner annu~ar top por~ion 49 with a cylindrical wall 44, and an outer annular skirt portion 45 projecting downwardly ~rom the top portion 49. The two parts 49, 44 and 45 may be ~ormed integrally as a single one piece moulding (see Figure 4), or produced separately and assembled together. The inner wall 44 makes a snap ~it connection with the side wall 23 o~ the outer nozzle 18 and the outer wall 45 forms an outer decorative skirt. The inner wall 44 has a groove 46 on its inner surface that engages a bead 25, which may be a continuous bead or an interrupted bead, on the outer sur~ace o~ the side wall 23.
The cap 49 has a central aperture 47 through which portions 26 and 27 o~ the outer nozzle 18 project.
The lid 42 has a central annular side wall 48 which, in use, is concentric with the nozzle ori~ice 27 and has an annular resilient detent 51 projecting radially inwardly that is engagable with an external bead 52 surrounding the orifice 27 to hold the lid snapped shut over the ori~ice when the closure is in a closed condition, and which allows the lid to be flipped up to open the container 10 when required.
When the closure is in its open conditlon and both flexible tubular housings 12 and 14 are subject to pressure to expel their contents, the contents o~ the inner compartment 13 will be expelled through nozzle 20 and outlet passageway 32 and the contents of the outer compartment 11 will be expelled through passageway 31. The two separated contents will be held apart by the partition 28 but will combine on exiting the ori~ice 27.
With reference to Figure 4 there is shown a modi~ied container 110 and only the di~erences, as compared with the ~irst embodiment of the invention, will be described in detail.
The lid 142 included a central portion 143 which may be formed separately and then assembled to the outer portion of the lid 142. The central portion 143 on its side adjacent the nozzle has a pair of radially spaced annular sidewalls 147, 148 that are concentric with the nozzle orifice 127, and a f pair o~ diametrical walls 149 that align with the partition 128.
The sidewalls 147,148 engage the inside and outside CA 02237878 1998-0~-13 W O 97tl8138 PCT/GB96/02721 sur~aces, respectively, o~ the nozzle to seal the closure and the diametrical walls 149 engage each side o~ the partition to seal the passageways 31, 32 ~rom each other.
The inner tube outlet nozzle 120 has an inwardly projecting lip 121 at its outer end to sti~fen the no~le and help prevent retraction a~ter the nozzle has been assembled into the passageway 32 when the discontinuous bead 137 snaps into cooperating groove 146.
With re~erence to Figure 5 there is shown a closure 240 in which the cap or lid 242 makes a screw-threaded connection with the outer shoulder piece 21~ which is provided with an external screw thread 225 on its cylindrical sidewall 223.
The lid 242 has a top portion 231 and an outer cylindrical sidewall 232. The sidewall 232 has an internal screw thread 233 which co-operates with the thread 225 on the shoulder piece 216 ~or sealing and opening the passageways 31, 32. The top portion 231 has an annular inner sidewall 248 which seals against the outer sur~ace o~ the nozzle ori~ice 227. A
circular seal wad 235 is located within the annular sidewall 248 against the top portion 231.
